+# MyNetTCPTable  
+
+MyNetTCPTable is a tcp_table service for postfix to allow matching networks from LDAP.  
+ldap_table does not allow to match network range, so you have to set all IPs in LDAP to use it.  
+MyNetTCPTable cover this use case, allowing you to put ipNetwork objects into LDAP in CIDR form and match unicast IP sent by postfix to these networks.
+
